It's a concern I have about deflationary currencies in general. It's not very common in the world right now so you could argue I'm speculating too, really.

You are talking about the singularity being the point that we switch to crypto currency. I suppose my argument is that the singularity may not come because of deflation counteracting and convincing people to continue holding.

All in all I'm glad it's been such a diplomatic discussion. I would engage people the same way if I were you and appreciate that you seek new information.
